I noticed that fasthttp was taking up 1.8MB of heap memory, even though it wasn't being used. This turned out to be the stackless function: 1.80MB github.com/valyala/fasthttp/stackless.NewFunc
Lazy load the stackless functions with sync.Once, given this a simple atomic read, it shouldn't affect performance for the fast-path (I haven't seen benchmarks with compression enabled).
